One platform, four businesses — Personal, Business, Wealth, Insurance — each with its own regulator and release calendar. Statements, policies and letters go out on a schedule customers notice the moment it slips.

So the job is to change it without pausing it. The move from Exstream Classic to Cloud Native was not a lift and shift: the template estate was rationalised on the way across, so what landed was smaller and more shared. It went in phases, each starting with its rollback plan, old and new running side by side until no customer could tell which had produced their document.
That only works if some things stay central. I keep template ownership, data formats and release cycles in one place — the three each business most wants to own, and the three that turn one platform into four. Cloud Native gave one of them back: business teams now change their own templates in Exstream Content Author, inside that governance rather than around it.
It is still one platform. Client confidential, so no link; the detail travels well in conversation.
